This study is a follow-up of previous studies conducted by the NIDR in Illinois in 1980 and 1985 and in Iowa in 1982 to assess the prevalence of dental fluorosis and dental caries among schoolchildren exposed to different concentrations of fluoride in their drinking water. Both Illinois surveys were carried out in the same communities, which had naturally occurring fluorides in their water supplies at concentrations of approximately one, two, three and four times that recommended as optimal for those areas. In contrast, the Iowa communities had negligible concentrations of fluoride in their drinking water. The need to monitor for possible changes in the prevalence of dental fluorosis continues to receive high priority. Additional research also is needed to further elucidate and define current interrelationships between dental caries, dental fluorosis, and various concentrations of fluoride in drinking water. The continued availability of the same communities in Illinois and the identification of two communities in Nebraska with negligible concentrations of water-borne fluoride have afforded an excellent opportunity to address these research needs. Examinations were completed in April 1990 on approximately 300 schoolchildren ages seven through 16 in the two Nebraska communities. Each child was examined for dental caries using the DMFS index and for dental fluorosis using both Dean's Index and the Tooth Surface Index of Fluorosis. Examinations, using the same indices, were conducted in October 1990 in Illinois. Data from all study sites currently are being analyzed.

这项研究是 NIDR 之前进行的研究的后续研究 1980 年和 1985 年伊利诺伊州以及 1982 年爱荷华州评估了 接触氟斑牙的学童和龋齿 饮用水中氟化物浓度不同。 两个都 伊利诺伊州的调查是在同一社区进行的，这些社区 供水中天然存在的氟化物浓度为 大约为推荐最佳值的一倍、二倍、三倍和四倍 对于那些地区。 相比之下，爱荷华州的社区可以忽略不计 饮用水中氟化物的浓度。 需要监测牙科患病率可能发生的变化 氟中毒继续受到高度重视。 额外的研究还有 需要进一步阐明和界定当前之间的相互关系 龋齿、氟斑牙以及各种浓度的氟化物 饮用水。 相同社区的持续可用性 伊利诺伊州和内布拉斯加州的两个社区的识别 水性氟化物的浓度可忽略不计 满足这些研究需求的绝佳机会。 考试是 1990 年 4 月完成，对象为约 300 名七岁小学生 内布拉斯加州两个社区的 16 人。 每个孩子都接受了检查 龋齿使用 DMFS 指数，氟斑牙则使用两者 Dean指数和氟中毒牙面指数。 考试， 1990 年 10 月在伊利诺伊州进行了使用相同指数的调查。 数据 目前正在对所有研究地点的数据进行分析。
